Add requisites to installation instructions

[JackNWhite]

Summary

Current instructions are:

1. Clone the source code
   git clone https://github.com/nasa/openmct.git

2. Install development Dependencies
   npm install

3. Run a local development server
   npm start

My example npm install log is:

npm WARN EBADENGINE Unsupported engine {
npm WARN EBADENGINE   package: '[email protected]',
npm WARN EBADENGINE   required: { node: '>=10.12.2 <16.0.0' },
npm WARN EBADENGINE   current: { node: 'v17.4.0', npm: '8.3.1' }
npm WARN EBADENGINE }
npm WARN deprecated [email protected]: The querystring API is considered Legacy. new code should use the URLSearchParams API instead.
npm WARN deprecated [email protected]: this library is no longer supported
npm WARN deprecated [email protected]: Removed event-stream from gulp-header
npm WARN deprecated [email protected]: CoffeeScript on NPM has moved to "coffeescript" (no hyphen)
npm WARN deprecated [email protected]: Please upgrade  to version 7 or higher.  Older versions may use Math.random() in certain circumstances, which is known to be problematic.  See https://v8.dev/blog/math-random for details.
npm WARN deprecated [email protected]: request has been deprecated, see https://github.com/request/request/issues/3142
npm WARN deprecated [email protected]: babel-eslint is now @babel/eslint-parser. This package will no longer receive updates.
npm WARN deprecated [email protected]: core-js@<3.4 is no longer maintained and not recommended for usage due to the number of issues. Because of the V8 engine whims, feature detection in old core-js versions could cause a slowdown up to 100x even if nothing is polyfilled. Please, upgrade your dependencies to the actual version of core-js.

In light of the above, and this issue, please add requisite software versions to the installation instructions.

Testing Instructions

Verify that main readme includes a blurb about supported node versions

Verified in Testathon on 01/24/22 - I see the text "Note: Check the package.json engine for our tested and supported node versions." in the README
